MATHEMATICS 1. Draw an abacus. Use it to illustrate the place value of each digit in the number 473,562. To illustrate 473,562 on an abacus, you would have rods representing place values, and beads on each rod. Hundred Thousands rod: 4 beads Ten Thousands rod: 7 beads Thousands rod: 3 beads Hundreds rod: 5 beads Tens rod: 6 beads Ones rod: 2 beads The place value of each digit in 473,562 is: 4 is in the hundred thousands* place. 7 is in the ten thousands* place. 3 is in the thousands* place. 5 is in the hundreds* place. 6 is in the tens* place. 2 is in the ones* place. 2. Write the number 314,789,123 in words. The number 314,789,123 in words is: Three hundred fourteen million, seven hundred eighty-nine thousand, one hundred twenty-three.* 3. A company paid 19,698,340 in tax. Round this amount to the nearest ten millions. Step 1: Identify the digit in the ten millions place. The number is 19,698,340. The digit in the ten millions place is 1. Step 2: Look at the digit to its right (the millions place). The digit to the right of 1 is 9. Step 3: Round up or down. Since 9 is 5 or greater, we round up the digit in the ten millions place. 1 becomes 2. All digits to the right become zeros. 19,698,340 ≈ 20,000,000 4. Find the sum of all prime numbers between 1 and 20. Step 1: List all prime numbers between 1 and 20. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The prime numbers between 1 and 20 are: 2, 3, 5, 7, 11, 13, 17, 19. Step 2: Sum these prime numbers. 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 5 + 5 + 7 + 11 + 13 + 17 + 19 10 + 7 + 11 + 13 + 17 + 19 17 + 11 + 13 + 17 + 19 28 + 13 + 17 + 19 41 + 17 + 19 58 + 19 = 77 Last free one today — make it count tomorrow, or type /upgrade for unlimited.
